IdealPhotonics' screw kits are a standard set of fastening components for optical/mechanical system assembly design (such as M3/M4/M6 stainless steel screws, washers, and wrenches). Through precise matching of materials (such as antimagnetic copper alloy) and specifications (such as countersunk/hex socket head caps), they ensure rigid connections and long-term stability in equipment assembly.These kits are compatible with all scenarios (standardized threads/lengths/hardness), feature corrosion-resistant treatments (such as passivation/nickel plating), and have anti-loosening designs (such as nylon locking mechanisms). They also offer portable, organized storage and resistance to tool scratches, improving the assembly efficiency and reliability of precision equipment.
